683687 ÷ 12 
We're looking to find how many times 12 goes into 683687.

On to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 12

Moving on to step 2:
12 goes into 68 5 times with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 60 from 68 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 12

On to step 3:
12 can be fit into 83 6 times, resulting in a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we take 72 away from 83, we end up with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 12

On to step 4:
116 divided by 12 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 569.0
Subtracting 108 from 116 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 12

Let's proceed to step 5:
88 divided by 12 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 5697.0
Subtract 84 from 88 to get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 12

Let's proceed to step 6:
12 can be fit into 47 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 56973.0
The remainder is 11 after subtracting 36 from 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 12 fits into 110 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 56973.9
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 12 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 56973.91
Subtracting 12 from 20 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 56973.916
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 56973.9166
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 56973.9166, with a leftover of 8e-05.
